The people who start complaining when prices go low are those who think of bitcoins as some sort of magic. They think that it will only go up and everyone will make profit only. They want to double or triple their money in just few days.

Till now, they were speaking against bitcoins and calling it scam and bubble. Now that it is giving so much good returns that even banks to invest in it.

In an unemployed guy can arrange some money for investing in bitcoins, this can be a good option. But I would not suggest this to an unemployed person, he should look for a job first.
